The ActiveWire High Speed HDMI cable is our most advanced HDMI cable to date, guaranteeing pristine signal at long lengths. With its in-line equalisation chipset, ActiveWire cables filter electrical noise and interference that normally reduces cable bandwidth, allowing them to effectively boost transmission distance. The entire HDMI 1.4 feature set is supported, including Full HD 1080p video, 3D content, and Audio Return Channel (ARC). The dedicated data channel, known as the HDMI Ethernet Channel for device networking, is also supported. ActiveWire HDMI cables can pass 4K Ultra HD resolutions with and without HDCP 2.2 copy protection (@60Hz 4:2:0 and @30Hz 4:4:4) up to a maximum of 20m in length .
